A function resource configuration method and device relate to the field of communications technologies, where the configuration method includes receiving, by a wearable device, a distribution request from a first terminal, where the distribution request requests the wearable device to distribute a first function resource of the wearable device to the first terminal, and the first function resource is already occupied by a second terminal, determining, by the wearable device based on the distribution request, whether to allow the first terminal to use the first function resource, and sending, by the wearable device, a notification message to the first terminal instructing the first terminal to use the first function resource when the wearable device allows the first terminal to use the first function resource.
